Refactor OllamaAPI and related classes to enhance tool management and request handling

Browse Source 
This update modifies the OllamaAPI class and associated request classes to improve the handling of tools. The ToolRegistry now manages a list of Tools.Tool objects instead of ToolSpecification, streamlining tool registration and retrieval. The OllamaGenerateRequest and OllamaChatRequest classes have been updated to reflect this change, ensuring consistency across the API. Additionally, several deprecated methods and commented-out code have been removed for clarity. Integration tests have been adjusted to accommodate these changes, enhancing overall test reliability.
